If your car really stinks n your too cheap to buy some top notch air spencers or similar or worse can't even find it, don't do no cabby pine tree hanging crap from the rear view Mirror
. Instead, go grab some of your mom's frebreeze and 2 sheets of bounce. Spray the trunk area, all the interior carpets with frebreeze, seats too (if they fabric), then stick a sheet of bounce under the seat. The car will smell great for months. That's the ghetto solution.
